2012 NMR Events

This is a non-exhaustive list of NMR related events taking place in 2012:

Myo-inositol and glycine relative content may help to grade astrocytic tumours.

Cover page of the Journal Belge de Radiologie - Belgisch Tijdschrift voor RadiologieNon-Invasive grading of astrocytic tumours from the relative contents of myo-inositol and glycine measured by in vivo MRS, Ana Paula Candiota, Carles Majós, Margarida Julià-Sapé, Miquel Cabañas, Juan José Acebes, Àngel Moreno-Torres, John R. Griffiths, Carles Arús; Journal Belge de Radiologie – Belgisch Tijdschrift voor Radiologie, 94, 319-329 (2011).  DOI: 10.5334/jbr-btr.698

MRI and MRS are established methodologies for evaluating intracranial lesions. One MR spectral feature suggested for in vivo grading of astrocytic tumours is the apparent myo-Inositol (mI) intensity (ca 3.55ppm) at short echo times, although glycine (gly) may also contribute in vivo to this resonance.

Classification of multiple sclerosis clinical forms by 1-H magnetic ressonance spectroscopy of cerebrospinal fluid

Fuzzy Sets and Systems journal Decision tree based fuzzy classifier of 1-H magnetic resonance spectra from cerebrospinal fluid samples , Francesc Xavier Aymerich, Juli Alonso, Miquel E. Cabañas, M. Comabella, P. Sobrevilla, Alex Rovira; Fuzzy Sets and Systems 170, 43-63 (2011). DOI: 10.1016/j.fss.2011.01.003

This paper presents a method for classifying cerebrospinal fluid (CSF) samples studied by proton magnetic resonance spectroscopy (1-H MRS) into clinical subgroups by means of a fuzzy classifier. The method focuses on the analysis of a low signal-to-noise region of the spectra and is designed to use a small number of samples because sampling can only be done through an invasive technique.

We are moving our web services (cont.)

This is the continuation of a previous post. If you missed it, I recommend reading it first and then resume reading this post where I explain the new wiki for our users, the forum for news and announcements, and the new version of the booking software.

A wiki for our users

Until now the information relevant to users was scattered (some say hidden) throughout the pages at our website, and its management was affected by the technical limitations I already mentioned in my earlier post. In an attempt to improve the situation, less than two years ago we started a wiki site to evaluate the possibility of using a wiki to handle the amount of information we generate.

We are moving our web services

We are relocating all our web services to a new server at http://sermn.uab.cat. At the same time we are upgrading the software or replacing it by better solutions when deemed advisable. While we are in the move, you can browse the old SeRMN website at http://sermn.uab.cat/rmn3.

Funny moving houseFor the last few years we have managed several web services hosted at different servers. The SeRMN web page was at http://rmn3.uab.cat, the instrument booking was at https://sermn02.uab.cat/bumblebee, and there were two mail lists for news and notices to P.I. () and users (). Then we added recently a wiki site at https://sermn02.uab.cat/sermn-dokuwiki to test whether it could be useful. It was clear that such multi-site situation had to come to an end the sooner the better, and now we are hard at work to make things much simpler.
